Each graphing mode has a unique equation editor. You must select the graphing mode and
Dec number base mode before you enter the functions. The TI -86 retains in memory all
equations stored to the Func , Pol , Param , and DifEq equation editors. Each mode also has
unique graph format settings and window variables.
Stat plot on àoff status, zoom factors, mode settings, and tolerance apply to all graphing
modes; changing the graphing mode does not affect them.
These mode settings affect graphing results.
♦
Radian or Degree angle mode affects the interpretation of some functions.
♦
dxDer1 or dxNDer differentiation mode affects plotting of selected functions.
